Discover Card holders: Sign up for July-September 5% Cashback Bonus

If you have a Discover Card, don’t forget to log in and then sign up to receive the July – September 5% cashback bonus on gas, theme parks, hotels and movies.

The 5% bonus is only good on the first $300 worth of purchases during July, August and September, but it’s better than nothing, right? And the 5% bonus on groceries returns in September too! Sign up for that starting August 1.
